mlm I've been doing extensive research on them and just about everyone is happy with them... haven't seen anything mentioned about bubbles though... what model or line are you looking at?
I am looking at the cs-6 24 inch high with the sedra 5000 pump. I did not mean that this skimmer made a lot of bubbles, I just want to make sur eit does not as the one I have now does.
I've run a EuroReef CS6-2 for close to a year now...absolutely zero problems with bubbles returning to my display. Excellant piece of equipment in my opinion. Definitely well worth the expense.
